Chrysler is recalling certain model year 2013 Ram 1500, 2500, and 3500 trucks manufactured September 9, 2012, through March 5, 2013 and equipped with optional premium tail lamps. In the affected vehicles, the turn signal indicator may not flash at a double rate to give a notification to the driver of a turn signal malfunction. Thus, these vehicles fail to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 108, “Lamps, reflective devices, and associated equipment.”
